Afghan demonstrators shout anti US-slogans during a protest against Koran desecration in Kunduz on February 25, 2012. Rock-throwing protesters attacked a UN compound and clashed with police in northern Afghanistan February 25, as a fifth day of protests over the burning of Korans left at least three dead. Thousands attacked the complex in Kunduz but did not get in as violence flared across the city, in unrest that raised to 27 the death toll from protests at Koran burning by troops from the US-led NATO force, according to an AFP tally.
